Here are the fasting plasma glucose levels for 18 diabetics enrolled in a diabetes control class, five months after the end of the class: 113 183 122 158 114 98 65 96 141 172 220 295 112 152 399 147 128 281 The study also measured the fasting plasma glucose of 16 diabetics who were given individual instruction on diabetes control. Here are the data: 128 158 169 180 240 163 164 188 165 148 253 241 243 246 247 158 Make a back-to-back stemplot to compare the class and individual instruction groups.
